UK Weather: Temperatures Could Soar to 29C in Early September, Met Office Forecasts

New projections suggest temperatures could climb to 28C in parts of England by September 5, potentially meeting the Met Office's heatwave threshold. The Met Office predicts 'very warm spells' early in the month, though rainfall is still expected, with unsettled conditions likely across the UK.

After a summer of record heat, the UK may see another warm spell in early September, according to fresh projections from WXCHARTS and the Met Office's long-range forecast.

Forecast maps indicate temperatures could reach 28C across southern and western England by September 5, with similar peaks extending as far north as Yorkshire the following day. By September 7, temperatures could hit 29C in eastern and western England, while central and southern areas may experience highs of 27-28C.

These figures would qualify as an official heatwave in some regions, as the Met Office defines a heatwave as meeting the 'heatwave threshold' for three consecutive days. The threshold is 28C in the south-east, decreasing to 25C elsewhere.

Despite the potentially hot start to the month, the Met Office's outlook for August 31 to September 9 warns of continued unsettled conditions, stating: 'Likely remaining unsettled with showers or longer spells of rain across all areas at times.' Rainfall amounts are predicted to be above average, with the wettest conditions in the northwest, and there is potential for strong winds at times.

The Met Office also noted that 'some drier and more settled interludes could develop, perhaps becoming longer in duration across southern areas later in this period.' Temperatures are expected to be near average overall, but 'some short-lived warm or very warm spells are possible, especially in the south.'

The warm forecast comes after a summer that saw temperatures exceed 34C on multiple days, according to reports. However, heavy rain and thunderstorms have caused disruption in recent days, with more intense downpours possible.

Looking ahead, the Met Office has warned of an unusually strong El Nino phenomenon, which could bring storms and rainfall this autumn and winter. Professor Adam Scaife, head of long-range forecasting at the Met Office, described the event as 'unprecedented,' noting that sea-surface temperatures in the equatorial Pacific could rise by more than 3C, far exceeding typical El Nino events.

Framing: Questions whether another heatwave will occur in September and presents the Met Office's forecast as the answer. — Reassuring yet cautionary

as of Aug 31, 2026, 9:16 PM UTC

Facts Included:

The Met Office has released its long-range forecast for September, predicting 'brief warm or very warm spells' in the beginning of the month.
The UK saw a record-breaking summer with temperatures reaching well over 34C on multiple days.
Heavy rain showers and gusty winds are expected to affect much of the south.
The Met Office said: 'As we head further into September, the distribution of rainfall becomes increasingly uncertain at this range.'
WX Charts predicted that temperatures could reach 25C again by September 5 in southern England.
'Intense' thunderstorms and heavy rain across much of England and Wales could cause travel disruption this week.
After five heat waves this summer, Brits were relieved when bands of heavy showers and thunderstorms began moving in last week.
The UK is bracing for a slew of storms and rainfall this autumn and winter brought by the El Nino phenomenon.
El Nino happens every three to seven years and shifts ocean winds.
The natural warming of sea temperatures is forecast to reach more than 3°C in the coming months, making this year's weather front 'the largest since the 19th century,' according to Met Office forecasters.
Professor Adam Scaife, Met Office's head of long range forecasting, said: 'We should be clear that this is an unprecedented event.'
Scaife added: 'A typical El Nino leads to an equatorial Pacific sea-surface temperature rise of between one to 2°C, with 2°C being a really big event.'
Scaife said: 'This implies that if the forecast is accurate – and other forecast systems show similar extreme values – then 2026 will far exceed our recent experience of El Nino and its worldwide climate effects.'

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the distinct outlets we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
